Skip Montanaro has a PyPI package, ‘lockfile’ (currently marked
“Beta”) <URL:http://pypi.python.org/pypi/lockfile> that has such
ambitions.
I think the interface he proposes is elegant and I intend to submit an
additional “PID File lock” capability, to cover the behaviour
expected of PID files in particular.
How should I alter this PEP if I'm proposing to use functionality
currently present in another package that exists only in PyPI?
Should I make an even lower-level PEP to suggest inclusion of Skip's
‘lockfile’ package? Is that wise? Is it polite?
